Definitions
- the invention relates to a grave lantern with a lantern body and a lantern.
- Grave lanterns are usually placed on a tombstone by screwing them firmly to the tombstone.
- Such an arrangement of the grave lantern is simple, but can not be adapted to the environment. For example, the grave lantern disappears under high-growth plants in its surroundings or in winter under a blanket of snow.
- the invention has for its object to provide a flexibly usable grave lantern.
- a grave lantern is provided with a lantern body and a lantern foot, wherein the lantern has at least two telescopically pluggable tubes, wherein a first tube on the lantern body and a second tube can be fixed to a bottom surface, and wherein a locking device is provided to to fix the first and the second tube in different extended positions relative to each other.
- the lantern body can be adjusted in height above the ground or a tombstone.
- the grave lantern can always be kept level or slightly above the top of an adjacent planting.
- the construction of the grave lantern according to the invention is structurally simple, since two telescopically pluggable tubes are provided for height adjustment, which can be fixed by means of a locking device in different far extended positions relative to each other. In the fully inserted position of the two tubes, the grave lantern is indistinguishable from a conventional, non-height adjustable grave lantern.
- the second tube has a conical tip with a passage opening.
- the second tube can be used for example as a so-called ground spike and be easily propelled into the soil.
- the arrangement of the second tube in a suitable foundation is possible.
- the locking device has at least one spreading device.
- the two telescopically plugged tubes can be locked together in a simple manner.
- the spreading device can be arranged on the inner tube of the telescopic device, so that it is invisible from the outside.
- the spreading device is on the one hand protected against environmental influences and pollution and on the other hand creates a visually appealing design of the telescopic device.
- the spreading device has at least one wedge element and an expansion sleeve.
- the inner tube can be locked to the outer tube.
- the wedge element can be displaced, for example by means of leverage or by means of a threaded rod relative to the expansion sleeve.
- the spreading device is provided on the first, fixable on the lantern body tube and is received in the second, fixable to the bottom surface of the tube.
- the spreading device is protected against contamination and fixed to the lantern body tube is inserted into the fixed fixed to the bottom surface of the tube.
- the fixed to the bottom surface pipe is thus always closed by the fixed to the lantern tube and thereby can be reliably prevented that moisture or contamination penetrates into the fixed pipe to the ground.
- a sliding seal between the two tubes may be provided to further improve the seal.
- the wedge element is rotatably arranged on a threaded rod fixed to the first tube.
- the wedge element can be moved in a very simple manner by rotating the two tubes relative to each other for the expansion sleeve.
- the expansion sleeve on a plurality of spreading elements which are interconnected by means of a spring ring.
- the locking device has at least one spreading device and at least one of the tubes has a projection extending into its interior, against which the spreading device acts.
- the spreading elements catch on the projection and thereby simultaneously block at least one wedge element.
- a threaded rod fixed to the first tube can then be rotated relative to the wedge element so that it shifts relative to the expansion elements and pushes them outward against the inner wall of the second tube.
- a section of the weld extending into the interior of the pipe can be used as a projection to secure the spreading device against rotation in the pipe.
- the projection extends helically or parallel to the longitudinal axis of the tube.
- the spreading device can be fixed relative to a rotation relative to the tubes and yet the spreading device can are still displaced in the interior of the tube in the longitudinal direction to allow the telescopic adjustment of the two nested tubes.
- the presentation of the Fig. 1 shows a sectional sectional view of a lantern 10, which has a first tube 12 and a second tube 14.
- the second tube 14 is formed as a so-called bottom tube and is at its in Fig. 1 upper end welded to a mounting flange 16.
- the mounting flange extends perpendicular to the longitudinal axis of the second tube 14.
- the mounting flange 16 opposite lower end of the second tube 14 is provided with a conical tip 18 having a conical portion and a cylindrical portion.
- a diameter at the foot of the conical section corresponds exactly to the outer diameter of the second tube 14.
- the outer diameter of the conical section corresponds to the inner diameter of the second tube 14, so that a circumferential shoulder is formed between the conical section and the cylindrical section.
- the cone tip 18 is inserted into the second tube 14 until its end rests against the peripheral shoulder.
- the diameter of the cylinder portion can be dimensioned so that the cone tip 18 is securely fixed in the second tube 14 by means of a press fit.
- the cone top 18 has a through hole 20 which connects the interior of the second tube 14 with the environment.
- the through hole 20 is arranged offset to a central longitudinal axis of the apex 18. If necessary, water that has penetrated into the interior of the second tube 14 can flow off again via the through-bore 20.
- the staggered arrangement of the through hole largely prevents that when inserting the second tube 14 into the ground or a foundation large amounts of dirt penetrate into the through hole 20.
- the second tube 14 can be sunk in a bore of a foundation and the mounting flange 16 is fastened to the top of the foundation by means of screws.
- the first tube 12 is at his, in the Fig. 1 upper end, which protrudes from the second tube 14, provided with a sealing plug 22 having a threaded bore.
- the closure plug 22 may be received in the first tube 12, for example by means of a press fit.
- a lantern body By means of the threaded bore in the sealing plug 22 and a fastening screw 24, a lantern body, not shown, can be attached to the first tube 12.
- the first tube 12 is also provided with a sealing plug 24, which is also provided with a threaded bore.
- a threaded rod 26 is screwed, which extends over the end of the first tube 12 into the second tube 14 into it.
- the threaded rod 26 is rotatably connected to the sealing plug 24 and thus the first tube 12.
- a spreading device with an expansion sleeve 28 and two wedge members 30 and 32 is provided on the threaded rod 26, a spreading device with an expansion sleeve 28 and two wedge members 30 and 32 is provided.
- the first wedge member 30 is located with the interposition of a washer 34 on the End face of the first tube 12 and on the front side of the sealing plug 24 at.
- the first wedge member 30 has a through hole with a larger diameter than the outer diameter of the threaded rod 26 and is thereby not in engagement with the thread of the threaded rod 26, but can be freely rotated on this.
- the second wedge member 32 is arranged, which is provided with a threaded rod 26 to the appropriate internal threaded bore. Therefore, when the threaded rod 26 and the second wedge member 32 are rotated relative to each other, the wedge member 32 moves along the threaded rod 26.
- the expansion sleeve 28 has a plurality of spreading elements 36, which are strip-shaped and are bevelled at opposite, in each case the wedge elements 30, 32 facing ends.
- the bevelled ends of the spreading elements 36 can thereby slide on the frustoconical outer surfaces of the wedge members 30, 32 along. If a distance between the two wedge elements 30, 32 is changed relative to one another, as a result the spreading elements 36 move outwards or inwards.
- the spreading elements 36 each have a center groove 38, in which a spring ring 40 is received.
- the spring ring 40 surrounds all wedge elements 36 and thereby biases them against the wedge elements 30, 32. Together with the spring ring 40, the wedge elements 36 thereby form the expansion sleeve 28.
- the spreading device in a position in which the outer surfaces of the spreading elements 36 are spaced from the inner wall of the second tube 14 and the first tube 12 can thereby be displaced within the second tube 14.
- the first tube 12 can therefore be pulled out to bring a mounted on the first tube 12 lantern body in a desired height.
- the first tube 12 is rotated clockwise against the second tube 14.
- the expansion sleeve 28 thereby increases its outer diameter until the wedge elements 36 rest against the inner wall of the second tube 14.
- the second tube 14 and the first tube 12 are fixed to one another.
- a relative rotation of the expansion sleeve 28 with the wedge elements 36 is achieved in that the second tube 14 is provided with a projecting into the interior projection 42 which extends substantially parallel to a central longitudinal axis of the two tubes 12, 14.
- This projection 42 is in the illustration of Fig. 1 only shown schematically.
- the protrusion 42 prevents the wedge members 36 from rotating upon rotation of the first tube 12. This also prevents co-rotation of the second wedge element 32, so that the threaded rod 26 is rotated relative to the second wedge element 32 and this is thereby moved in the direction of the first wedge element 30. As a result, the wedge elements are pressed outward and ensure a fixation of the first tube 12 and the second tube 14 relative to each other.
- the projection 42 is formed by the inside of a weld of the second tube 14. Surprisingly, it has been found that the portion of the weld extending into the interior longitudinally extending into the interior protrudes sufficiently far into the interior to hold the wedge members 36 when the first tube 12 is rotated relative to the second tube 14.
- a structurally simple, easy-to-use and reliable grave lantern is thereby created, which can be set and fixed in height above a floor surface.

Abstract
Description
Die Erfindung betrifft eine Grablaterne mit einem Laternenkörper sowie einem Laternenfuß.The invention relates to a grave lantern with a lantern body and a lantern.
Grablaternen werden üblicherweise auf einem Grabstein dadurch angeordnet, dass sie fest an den Grabstein angeschraubt werden. Eine solche Anordnung der Grablaterne ist einfach, kann aber nicht an die Umgebung angepasst werden. So verschwindet die Grablaterne beispielsweise unter hoch wachsenden Pflanzen in ihrer Umgebung oder im Winter unter einer Schneedecke.Grave lanterns are usually placed on a tombstone by screwing them firmly to the tombstone. Such an arrangement of the grave lantern is simple, but can not be adapted to the environment. For example, the grave lantern disappears under high-growth plants in its surroundings or in winter under a blanket of snow.
Der Erfindung liegt die Aufgabe zugrunde eine flexibel einsetzbare Grablaterne bereitzustellen.The invention has for its object to provide a flexibly usable grave lantern.
Erfindungsgemäß ist hierzu eine Grablaterne mit einem Laternenkörper sowie einem Laternenfuß vorgesehen, wobei der Laternenfuß wenigstens zwei teleskopartig ineinander steckbare Rohre aufweist, wobei ein erstes Rohr am Laternenkörper und ein zweites Rohr an einer Bodenfläche fixierbar ist, und wobei eine Arretiervorrichtung vorgesehen ist, um das erste und das zweite Rohr in unterschiedlich weit ausgezogenen Stellungen relativ zueinander zu fixieren.According to the invention, a grave lantern is provided with a lantern body and a lantern foot, wherein the lantern has at least two telescopically pluggable tubes, wherein a first tube on the lantern body and a second tube can be fixed to a bottom surface, and wherein a locking device is provided to to fix the first and the second tube in different extended positions relative to each other.
Durch diese Maßnahmen kann der Laternenkörper in seiner Höhe über dem Erdboden oder einem Grabstein eingestellt werden. Auf diese Weise kann die Grablaterne beispielsweise immer auf Höhe oder leicht über der Oberkante einer benachbarten Bepflanzung gehalten werden. Speziell im Winter und bei großem Schneefall ist es möglich, die Grablaterne immer oberhalb der Schneeoberfläche zu halten. Der Aufbau der erfindungsgemäßen Grablaterne ist dabei konstruktiv einfach, da zur Höhenverstellung zwei teleskopartig ineinander steckbare Rohre vorgesehen sind, die mittels einer Arretiervorrichtung in unterschiedlich weit ausgezogenen Stellungen relativ zueinander fixiert werden können. In der vollständig eingeschobenen Stellung der beiden Rohre ist die Grablaterne nicht von einer konventionellen, nicht in der Höhe einstellbaren Grablaterne zu unterscheiden.Through these measures, the lantern body can be adjusted in height above the ground or a tombstone. In this way, for example, the grave lantern can always be kept level or slightly above the top of an adjacent planting. Especially in winter and during heavy snowfall, it is possible to keep the grave lantern always above the snow surface. The construction of the grave lantern according to the invention is structurally simple, since two telescopically pluggable tubes are provided for height adjustment, which can be fixed by means of a locking device in different far extended positions relative to each other. In the fully inserted position of the two tubes, the grave lantern is indistinguishable from a conventional, non-height adjustable grave lantern.
In Weiterbildung der Erfindung weist das zweite Rohr eine kegelartige Spitze mit einer Durchgangsöffnung auf.In a further development of the invention, the second tube has a conical tip with a passage opening.
Auf diese Weise kann das zweite Rohr beispielsweise als sogenannter Erdspieß genutzt werden und in einfacher Weise in das Erdreich vorgetrieben werden. Selbstverständlich ist aber auch die Anordnung des zweiten Rohres in einem geeigneten Fundament möglich. Indem in der kegelartigen Spitze eine Durchgangsöffnung vorgesehen ist, kann Kondenswasser oder in das zweite Rohr eindringendes Wasser wieder ablaufen. Dies ist vor allem im Winter von Bedeutung, wenn eindringendes Wasser gefrieren kann und die Teleskopanordnung blockieren könnte.In this way, the second tube can be used for example as a so-called ground spike and be easily propelled into the soil. Of course, however, the arrangement of the second tube in a suitable foundation is possible. By providing a passage opening in the conical tip, condensation water or water penetrating into the second tube can drain off again. This is especially important in winter, when penetrating water can freeze and block the telescope assembly.
In Weiterbildung der Erfindung weist die Arretiervorrichtung wenigstens eine Spreizvorrichtung auf.In a further development of the invention, the locking device has at least one spreading device.
Auf diese Weise können die beiden teleskopartig ineinander steckbaren Rohre in einfacher Weise aneinander arretiert werden. Vor allem kann die Spreizvorrichtung am inneren Rohr der Teleskopvorrichtung angeordnet werden, so dass diese von außen unsichtbar ist. Dadurch ist die Spreizvorrichtung zum einen gegenüber Umwelteinflüssen und Verschmutzung geschützt und zum anderen entsteht eine optisch ansprechende Gestaltung der Teleskopvorrichtung.In this way, the two telescopically plugged tubes can be locked together in a simple manner. Above all, the spreading device can be arranged on the inner tube of the telescopic device, so that it is invisible from the outside. As a result, the spreading device is on the one hand protected against environmental influences and pollution and on the other hand creates a visually appealing design of the telescopic device.
In Weiterbildung der Erfindung weist die Spreizvorrichtung wenigstens ein Keilelement und eine Spreizhülse auf.In a further development of the invention, the spreading device has at least one wedge element and an expansion sleeve.
Auf diese Weise kann durch relative Verschiebung des Keilelements und der Spreizhülse das innere Rohr am äußeren Rohr arretiert werden. Das Keilelement kann beispielsweise mittels Hebelwirkung oder mittels einer Gewindestange relativ zur Spreizhülse verschoben werden.In this way, by relative displacement of the wedge element and the expansion sleeve, the inner tube can be locked to the outer tube. The wedge element can be displaced, for example by means of leverage or by means of a threaded rod relative to the expansion sleeve.
In Weiterbildung der Erfindung ist die Spreizvorrichtung an dem ersten, am Laternenkörper fixierbaren Rohr vorgesehen und ist in dem zweiten, an der Bodenfläche fixierbaren Rohr aufgenommen.In a further development of the invention, the spreading device is provided on the first, fixable on the lantern body tube and is received in the second, fixable to the bottom surface of the tube.
Auf diese Weise ist die Spreizvorrichtung gegen Verschmutzung geschützt und das am Laternenkörper fixierte Rohr wird in das fest an der Bodenfläche fixierte Rohr eingeschoben. Das an der Bodenfläche fixierte Rohr ist damit stets durch das am Laternenkörper fixierte Rohr verschlossen und dadurch kann zuverlässig verhindert werden, dass Feuchtigkeit oder Verschmutzung in das am Boden fixierte Rohr eindringt. Selbstverständlich kann eine Gleitdichtung zwischen den beiden Rohren vorgesehen sein, um die Abdichtung weiter zu verbessern.In this way, the spreading device is protected against contamination and fixed to the lantern body tube is inserted into the fixed fixed to the bottom surface of the tube. The fixed to the bottom surface pipe is thus always closed by the fixed to the lantern tube and thereby can be reliably prevented that moisture or contamination penetrates into the fixed pipe to the ground. Of course, a sliding seal between the two tubes may be provided to further improve the seal.
In Weiterbildung der Erfindung ist das Keilelement drehbar auf einer am ersten Rohr fixierten Gewindestange angeordnet.In a further development of the invention, the wedge element is rotatably arranged on a threaded rod fixed to the first tube.
Auf diese Weise kann das Keilelement in sehr einfacher Weise durch Verdrehen der beiden Rohre zueinander relativ zur Spreizhülse verschoben werden.In this way, the wedge element can be moved in a very simple manner by rotating the two tubes relative to each other for the expansion sleeve.
In Weiterbildung der Erfindung weist die Spreizhülse mehrere Spreizelemente auf, die mittels eines Federrings miteinander verbunden sind.In a further development of the invention, the expansion sleeve on a plurality of spreading elements, which are interconnected by means of a spring ring.
Auf diese Weise kann eine konstruktiv einfache und zuverlässige Spreizvorrichtung bereitgestellt werden.In this way, a structurally simple and reliable spreading device can be provided.
In Weiterbildung der Erfindung weist die Arretiervorrichtung wenigstens eine Spreizvorrichtung auf und wenigstens eines der Rohre weist einen sich in seinen Innenraum erstreckenden Vorsprung auf, an dem die Spreizvorrichtung angreift. Auf diese Weise kann sichergestellt werden, dass ein relatives Verdrehen der Spreizvorrichtung gegenüber einem der beiden Rohre möglich ist. Beispielsweise verhaken sich die Spreizelemente an dem Vorsprung und blockieren dadurch gleichzeitig wenigstens ein Keilelement. Eine am ersten Rohr fixierte Gewindestange kann dann relativ zu dem Keilelement verdreht werden, so dass dieses sich relativ zu den Spreizelementen verschiebt und diese nach außen, gegen die Innenwand des zweiten Rohres drückt. Bei längs geschweißten Rohren kann ein sich in den Innenraum des Rohres hinein erstreckender Abschnitt der Schweißnaht als Vorsprung genutzt werden, um die Spreizvorrichtung gegen Rotation im Rohr zu sichern.In a further development of the invention, the locking device has at least one spreading device and at least one of the tubes has a projection extending into its interior, against which the spreading device acts. In this way it can be ensured that a relative rotation of the spreading device relative to one of the two tubes is possible. For example, the spreading elements catch on the projection and thereby simultaneously block at least one wedge element. A threaded rod fixed to the first tube can then be rotated relative to the wedge element so that it shifts relative to the expansion elements and pushes them outward against the inner wall of the second tube. In longitudinally welded pipes, a section of the weld extending into the interior of the pipe can be used as a projection to secure the spreading device against rotation in the pipe.
In Weiterbildung der Erfindung erstreckt sich der Vorsprung schraubenförmig oder parallel zur Längsachse des Rohres.In a further development of the invention, the projection extends helically or parallel to the longitudinal axis of the tube.
Sowohl mit einem sich schraubenförmig erstreckenden Vorsprung als auch mit einem sich parallel zur Längsachse des Rohres erstreckenden Vorsprung kann die Spreizvorrichtung gegenüber einer Drehung relativ zu den Rohren fixiert werden und dennoch kann die Spreizvorrichtung noch im Innenraum des Rohres in Längsrichtung verschoben werden, um die teleskopartige Verstellung der beiden ineinandergesteckten Rohre zu ermöglichen.Both with a helically extending projection and with a projection extending parallel to the longitudinal axis of the tube, the spreading device can be fixed relative to a rotation relative to the tubes and yet the spreading device can are still displaced in the interior of the tube in the longitudinal direction to allow the telescopic adjustment of the two nested tubes.

An seinem, in der
Auf der Gewindestange 26 ist eine Spreizvorrichtung mit einer Spreizhülse 28 und zwei Keilelementen 30 und 32 vorgesehen. Das erste Keilelement 30 liegt unter Zwischenfügung einer Beilagscheibe 34 an der Stirnseite des ersten Rohres 12 bzw. an der Stirnseite des Verschlussstopfens 24 an. Das erste Keilelement 30 weist eine Durchgangsbohrung mit größerem Durchmesser als der Außendurchmesser der Gewindestange 26 auf und ist dadurch nicht in Eingriff mit dem Gewinde der Gewindestange 26, sondern kann auf dieser frei verdreht werden. Am freien Ende der Gewindestange 26 ist das zweite Keilelement 32 angeordnet, das mit einer zur Gewindestange 26 passenden Innengewindebohrung versehen ist. Werden die Gewindestange 26 und das zweite Keilelement 32 daher relativ zueinander verdreht, bewegt sich das Keilelement 32 entlang der Gewindestange 26.On the threaded
Die Spreizhülse 28 weist mehrere Spreizelemente 36 auf, die leistenförmig ausgebildet sind und an gegenüber liegenden, jeweils den Keilelementen 30, 32 zugewandten Enden abgeschrägt sind. Die abgeschrägten Enden der Spreizelemente 36 können dadurch auf den kegelstumpfförmigen Außenflächen der Keilelemente 30, 32 entlang gleiten. Wird ein Abstand der beiden Keilelemente 30, 32 zueinander verändert, bewegen sich infolgedessen die Spreizelemente 36 nach außen bzw. innen. Die Spreizelemente 36 weisen jeweils eine Mittelnut 38 auf, in der ein Federring 40 aufgenommen ist. Der Federring 40 umgibt alle Keilelemente 36 und spannt diese dadurch gegen die Keilelemente 30, 32 vor. Zusammen mit dem Federring 40 bilden die Keilelemente 36 dadurch die Spreizhülse 28.The

Eine relative Verdrehung der Spreizhülse 28 mit den Keilelementen 36 wird dabei dadurch erreicht, dass das zweite Rohr 14 mit einem in den Innenraum hinein ragenden Vorsprung 42 versehen ist, der sich im Wesentlichen parallel zu einer Mittellängsachse der beiden Rohre 12, 14 erstreckt. Dieser Vorsprung 42 ist in der Darstellung der
Auch bei einer Drehung des ersten Rohres 12 im Gegenuhrzeigersinn verhaken die Keilelemente 36 wieder an dem Vorsprung 42, so dass eine relative Drehung von Gewindestange 26 und zweitem Keilelement 32 erreicht wird. Das zweite Keilelement 32 entfernt sich dadurch von dem ersten Keilelement 30 und die Spreizelemente 36 können sich, vorgespannt von der Ringfeder 40, wieder nach innen bewegen. Sobald die Spreizelemente 36 dann ausgehend von der in
Der Vorsprung 42 ist dabei durch die Innenseite einer Schweißnaht des zweiten Rohres 14 gebildet. Überraschenderweise hat sich herausgestellt, dass der sich in den Innenraum längs geschweißter Rohre hinein erstreckende Abschnitt der Schweißnaht ausreichend weit in den Innenraum vorragt, um die Keilelemente 36 festzuhalten, wenn das erste Rohr 12 relativ zum zweiten Rohr 14 verdreht wird.The
Mit der Erfindung wird dadurch eine konstruktiv einfache, leicht zu bedienende und dabei zuverlässige Grablaterne geschaffen, die in der Höhe über einer Bodenfläche eingestellt und fixiert werden kann.With the invention, a structurally simple, easy-to-use and reliable grave lantern is thereby created, which can be set and fixed in height above a floor surface.
